An air-purifying respirator is a type of respiratory protective equipment that filters or purifies the air inhaled by the wearer. Of the options listed, only non-powered particulate respirators are classified as air-purifying respirators. Supplied-air respirators use an external source of air and do not filter the air, while powered air-purifying respirators use a blower to drive the air through a filter. Additionally, self-contained breathing apparatuses are not considered air-purifying respirators as they provide a supply of independent air and do not rely on filtration.
